C# Класс Encog.App.Analyst.CSV.Balance.BalanceCSV

Balance a CSV file. This utility is useful when you have several an unbalanced training set. You may have a large number of one particular class, and many fewer elements of other classes. This can hinder many Machine Learning methods. This class can be used to balance the data. Obviously this class cannot generate data. You must request how many items you want per class. Some classes will have lower than this number if they were already below the specified amount. Any class above this amount will be trimmed to that amount.
